A level 1 and level 2 are issued for a large region between NE Spain (Catalonia), Germany, W Romania and Italy for excessive convective precipitation and large hail.

A level 2 was issued across parts of Belgium, Luxembourg and CNTRL-Germany mainly for excessive rain.
A level 1 surrounds the level 2 areas with similar hazards but lower probabilities. In addition a few severe wind gust and large hail events are possible and an isolated tornado event over S-UK can't be excluded.

A level 2 was issued across parts of Germany and the Northeast Netherlands mainly for extreme rainfall, and to a lesser extent for large hail.
A level 1 was issued across large portions of Central Europe and the West Balkans for extreme rainfall and large hail. 

"If you are interested in the convective parameters which we use for forecasting severe thunderstorms in Europe check out new research paper "Climatological Aspects of Convective Parameters over Europe: A Comparison of ERA-Interim and Sounding Data " co-authored by the members of ESTOFEX.

Convective coverage has increased markedly over the MD area, with a line of supercells stretching from Luxembourg southward across Northeast France. In addition, new cells initiating over Luxembourg and a small MCS over Central Belgium is moving northward.
